MATERIAL FOR APPLYING OIL TO AXLE-BEARINGS.

Specification of Letters Patent.

Patented Nov. 28, 1905.

Application filed November 1'7, 1904. Serial No. 233,054:-

To all whom it may concern:

Be it known that I, WILLIAM ERNEST LAY- oooK, a subject of the King ofGreat Britain, residing at Sheflield, England, have invented certain newand useful Improvements in the Manufacture of Material for Applying Oilto Axle-Bearings, of which the following is a specification.

This invention relates to a new product for use in the filling ofjournal-boxes or in other positions where a lubricant is to be applied,and to a process of preparing such an improved filling. The materialgenerally in use at present for this purpose is cotton-waste, and thisquickly loses its springiness and sinks, and thus fails to effect theintended object, which is to raise the lubricant by capillary action andapply it to-the axle. This failure is a common cause of axles becomingoverheated.

The present invention provides a combination of elastic fiberssuch, forexample, as horsehair or other hair with fibers of absorbentmaterialsuch, for example, as woolen threads or waste, the two beingspun together and the elastic fibers being preferably given a permanentcurly set and the mass being then carded or teased into a loose opencondition. The elastic fibers constitute a substantially permanentelastic medium which prevents the mass from sinking and packing andkeeps it in constant contact with the axle, the woolen or otherabsorbent fibers serving to carry the oil up from the box by capillaryaction. The curled elastic medium is thoroughly intermingled with theabsorbent medium, so as to make the entire ma'ss homogeneously elastic.

The accompanying drawings illustrate the manufacture of the improvedfilling, being chiefly diagrammatic.

Figure 1 illustrates the successive steps of forming the curl. Fig. 2illustrates the soaking of the curl, and Fig. 3 the drying of the curl.Fig. etillustrates the commercial product and the manner of using it.

Referring to the drawings, threads of wool or the like are indicated atA and threads of horsehair or the like at B. A suitably-proportionednumber ofthese hairs are carded together in order to effectually mix thetwo materials without damaging the Wool, and by any usual or suitablemeans, such as are common in spinning machinery, are then twistedtightly together to form a sort of rope C and then crimped into a kinkycurl D, so that when opened out for use they assume the appearance of aloose open mass of spirals. Suitable lengths of this curl are thensoaked in water, as indicated in Fig. 2, which softens the hair in itsspun position. Thereupon the curl is taken out of the water and put intoan oven or other drying apparatus, which is indicated in Fig. 3 with agas-heater underneath for the sake of illustration. When dried, the hairwill be found to have a permanent set in its spun and curled position.These curls of material are preferably the form of the product in whichit is marketed. They are very compact and make the handling andtransportation of the product simple and cheap. In use the end of thecurl will be untwisted to what is termed the soft curl and teased orcarded in the manner indicated at E to form an open loose bulk such asis required to be put into the journal-boxes, and where customers havenot conveniently the means of teasing or carding it I propose to marketit in the open loose condition indicated at E.

Though I have described with great particularity of detail certainembodiments of the invention, yet it is not to be understood therefromthat the invention is limited to the specific embodiments disclosed.

Various modifications may be made by those skilled in the art withoutdeparture from the invention.

What I claim is 1. The improved material for applying oil toaxle-bearings, consisting of elastic fibers and fibers of absorbentmaterial spun together.

2. The improved material for applying oil to axle-bearings, consistingof elastic hair and fibers of absorbent material spun together.

3. The improved material for applying oil to axle-bearings, consistingof elastic fibers and fibers of absorbent material spun together, in acompact curl.

4. The improved material for applying oil to axle-bearings, consistingof elastic fibers and fibers of absorbent material spun together, theelastic fibers having a permanent set in their spun position.
